Product details
Overview
1N5393G-T from Diodes Incorporated is a 200 V, 1.5 A glass passivated general-purpose rectifier diode in DO-15 package, featuring 1.1 V forward voltage at 1.5 A, 5 µA reverse leakage at 25°C, and 50 A non-repetitive surge capability - used in AC/DC input stage rectification for industrial power supplies and LED drivers.
For engineers reviewing the 1N5393G-T datasheet, 1N5393G-T pinout, 1N5393G-T application, or 1N5393G-T equivalent, key selection criteria include peak reverse voltage rating, thermal resistance (80 °C/W), forward voltage drop under load, surge robustness, and DO-15 mechanical compatibility with legacy through-hole PCB layouts.
Technical Context
This device operates as a single-phase, half-wave silicon rectifier optimized for 60 Hz line-frequency applications. Its glass passivation ensures stable junction performance under humidity and thermal cycling, while the DO-15 package supports lead-free reflow and wave soldering per MIL-STD-202.
The 200 V DC blocking voltage (VR) and 140 V RMS rating enable use in 115 VAC and 230 VAC front-end rectification with margin. Derating to 1.5 A requires ambient temperature ≤55°C with leads held at ambient at 9.5 mm from case per Note 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse voltage before breakdown; sets safe operating limit for 230 VAC input with 1.4× peak derating. |
| IO @ TA=55°C | 1.5 A - Continuous average forward current with thermal constraint; defines usable output capacity in unheatsinked designs. |
| VFM @ IF=1.5A | 1.1 V - Forward voltage drop at rated current; determines conduction loss (1.65 W) and thermal rise in linear rectifier stages. |
| IFSM | 50 A - Non-repetitive surge rating for 8.3 ms half-sine; withstands inrush from cold-start capacitive loads. |
| RθJA | 80 °C/W - Junction-to-ambient thermal resistance; predicts ~132 °C junction rise above ambient at full load without heatsinking. |
| IRM @ 25°C | 5 µA - Reverse leakage at rated VR; ensures minimal standby power loss in high-impedance hold-up circuits. |
Pinout & Package
Package: DO-15 molded plastic case (UL 94V-0), axial leads, cathode band marking, 0.4 g mass. Lead finish: matte tin, solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC source or transformer secondary; polarity-sensitive for correct rectification direction. |
| Cathode | Forward current exit / reverse-blocking terminal | Marked with band; ties to positive rail or smoothing capacitor input; blocks reverse voltage up to 200 V. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Prevents moisture-induced junction degradation and improves long-term reliability in humid environments. |
| 50 A surge rating | Supports repeated cold-start events in offline SMPS and lighting ballasts without parametric shift or failure. |
| Low 5 µA IRM | Minimizes reverse-bias power dissipation in high-impedance bias networks and signal-level clamping circuits. |
| DO-15 mechanical standard | Ensures drop-in replacement compatibility with legacy board footprints and automated axial insertion equipment. |
Applications
| AC/DC Power Adapter Input Stage | LED Driver Bulk Rectification |
|---|---|
Use Scenario: 115/230 VAC input rectification feeding capacitor-input filter in wall-wart adapters. IC Role / Device Role / Timing Role: General-purpose rectifier converting AC line to pulsating DC prior to regulation. Use Value: 200 V VRRM provides 1.7× margin over 230 VAC peak (325 V), and 1.1 V VFM limits conduction loss to <1.7 W at full load. | Use Scenario: Off-line LED driver with bridge or single-diode rectification feeding constant-current buck controller. IC Role / Device Role / Timing Role: High-reliability line-frequency rectifier handling 1.5 A continuous current into bulk storage capacitor. Use Value: Glass passivation prevents parameter drift during thermal cycling in enclosed luminaires; 50 A IFSM absorbs capacitor inrush. |
| Industrial Control Power Supply | Appliance Motor Drive Front-End |
Use Scenario: Auxiliary 24 V supply in PLC I/O modules powered from 115 VAC control bus. IC Role / Device Role / Timing Role: Primary rectifier in unregulated linear or flyback-derived auxiliary supply. Use Value: 80 °C/W RθJA enables operation at 55°C ambient without heatsink; DO-15 fits constrained board space. | Use Scenario: Rectification stage in universal motor speed controllers for kitchen appliances. IC Role / Device Role / Timing Role: Half-wave or full-wave rectifier supplying DC link for TRIAC or MOSFET phase-control circuitry. Use Value: Low 5 µA IRM avoids false triggering of zero-cross detection; robust surge rating handles motor startup transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar general-purpose rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4003-T | 50 V VRRM, same DO-15 package and 1.5 A IO rating | Only suitable for ≤35 VAC systems; insufficient for 115/230 VAC inputs | Select only for low-voltage AC-fed logic supplies or signal-level clamping where 200 V rating is unnecessary. |
| 1N5403G-T | 200 V VRRM but 3 A IO rating and larger DO-201AD package | Higher current capacity requires PCB pad and trace redesign; not footprint-compatible | Choose when thermal headroom or future current scaling is required; verify mechanical clearance and solder joint reliability. |
Compared with 1N4003-T and 1N5403G-T, the 1N5393G-T uniquely balances 200 V blocking, 1.5 A current, DO-15 footprint, and glass passivation - making it optimal for cost-sensitive, space-constrained 115/230 VAC rectification where surge robustness and long-term stability are critical.

FAQ
Is the 1N5393G-T RoHS compliant?
Yes, the 1N5393G-T features a lead-free finish and complies with RoHS Directive 2011/65/EU (Revision 13.2.2003), including exemptions for glass and high-temperature solder per EU Annex Notes 5 and 7. Tin-plated leads meet MIL-STD-202 solderability requirements.
What is the maximum ambient temperature for full 1.5 A operation?
Full 1.5 A average forward current is rated at TA = 55°C, provided leads are maintained at ambient temperature at a distance of 9.5 mm from the case body. Above 55°C, current must be linearly derated to zero at 175°C per Figure 1 in the datasheet.
Can the 1N5393G-T replace a 1N4007 in a 230 VAC application?
No - the 1N4007 has 1000 V VRRM, while the 1N5393G-T is rated for 200 V. In a 230 VAC system, peak voltage reaches ~325 V; using the 1N5393G-T would exceed its 200 V VRRM and risk catastrophic failure. A 1N5397G-T (600 V) or 1N4007 is required instead.
Why is this part marked "NOT RECOMMENDED FOR NEW DESIGN"?
Diodes Incorporated designates the 1N539xG series as "NOT RECOMMENDED FOR NEW DESIGN" due to industry migration toward higher-efficiency alternatives (e.g., fast recovery or Schottky diodes) and newer packaging formats. However, it remains fully qualified, in active production, and supported for legacy repair, maintenance, and cost-driven volume applications.
